  • Another object of the invention is to provide a method for Manufacture of a one-piece row from several protective elements extensive freedom in design and cost-effective production. This task is accomplished by a foldable protective element for cables solved the claim 1. Several such protective elements can form one one-piece row of protective elements are formed according to claim 11, a corresponding method is specified in claim 21.
  • a foldable protective element according to the invention is made of plastic in the essentially molded in one piece or in a flat planar configuration cast and is made of interconnected by bendable bridges Segments built.
  • the protective element has a base segment a bottom and a top and at least one wall segment, which by bending and / or folding towards the top of the bottom segment and mechanically closing a locking mechanism to a closed one Channel section can be shaped.
  • the protective element is included either connected to other similar protective elements or something trained that it can be connected to other similar protective elements, so that the channel sections in a longitudinal direction a channel for lines form, especially for flexible cables.
  • the protective element can consist of a base segment and a wall segment formed thereon on one side, which kinked to the top during assembly, formed into an arch and attached the opposite side of the floor segment by means of a locking mechanism is hooked or snapped into place.
  • a section of canal thus created with an approximately semicircular cross section forms the simplest form of a Protection element for movably laid cables.
  • this can consist of a floor segment and two wall segments that either molded onto different sides of the bottom segment and are interconnectable by a locking mechanism or both are integrally formed on one side of the base segment and by two Wrinkles can be brought into the desired shape.
  • the protective element In order to obtain a protective element which is approximately rectangular in cross section, as is the case is preferred for moveable cables, the protective element must be Floor segment, at least two wall segments and a cover segment exhibit. These can be distributed in different ways on the floor segment be molded, as will be explained in more detail with reference to the drawing.
  • the bendable bridges between the individual segments are not designed for multiple back and forth bending must be, but only a one-time folding in one direction have to survive without damage. It is therefore possible through suitable shaping of the bridges to produce very stable protective elements, which in their mechanical properties directly U-shaped chain links are quite similar, provided the stability of the folded composite ultimately is ensured by the locking mechanism.
  • This is preferably one Device for locking, hooking and / or locking, in particular one secured against unintentional loosening under load Manufacture device. Whether the locking mechanism after closing should be designed to be manually detachable, depends on the respective intended Use case.
  • the invention is particularly economical Energy supply systems is suitable, in which a repair in generally not considered, but only damaged systems can be completely replaced.
  • the invention also leaves all kinds of known detachable connections as a locking mechanism, the type of manufacture even in a flat, planar configuration allows additional degrees of freedom in the design of the locking mechanism.
  • the individual segments of the protective element with molded parts, in particular Ridges, projections, recesses and the like may be provided by which ensures the exact folding.
  • Such molded parts can additionally improve the stability of the individual segments by Form braces.
  • separators it is also known for energy supply systems, so-called separators to be given which different lines within the protective element separate from each other what a defined and gentle course of the Allows cables inside the protection system.
  • Such dividers that the channel section to be formed in two or more partial cross-sectional areas can divide according to the present invention to at least one of the segments are molded.
  • Such a separator can either be molded onto one of the segments of the protective element that he already from the plane of the two-dimensional configuration during manufacture approximately perpendicular protrudes, or it can be molded onto one of the segments, that it can later be folded into the desired position.
  • the bridges connecting the segments are a protective element at least partially knee joints, i.e. Joints because of their design can remain stable in two different positions.
  • Such Joints are, for example, from the prior art for plastic closures known for bottles. Especially when used for fastening of cover segments on protective elements according to the invention there are considerable advantages, especially when assembling the system.
  • Another embodiment of the invention provides that the protective element Guide openings for receiving at least one guide band or guide thread for stringing together many protective elements.
  • protective elements can be made in this way thread on a guide tape or on guide threads, creating a simple protection system is formed.

  • These flexible sections then take over Function of joints, but, like the one-piece arrangement, have the advantage that no parts rub against each other, so that no abrasion arises and also no tolerances that change due to wear occur. This can be used for small precision systems and in Clean rooms in which abrasion is undesirable can be of great advantage.
  • the rows of Means known in the prior art for limiting the radius of curvature be used.
  • Webs can be arranged that interact with adjacent webs so that the row of protective elements only up to a predetermined minimum radius of curvature can be bent towards the bottom.
  • These bridges can run in the longitudinal direction and according to the desired Have angles to the neighboring element beveled end faces.
  • Another An alternative is that the webs run transversely to the longitudinal direction and accordingly have bevelled sides.
  • energy supply systems with a minimal to one side Radius of curvature it is often desirable that these systems Only move up to a straight line at the top to let. In this way, energy supply systems can even be considered load-bearing Structure for lines serve, the largest possible so-called unsupported length is desired. Because the weight of the cables to be led and the guide system even with longer unsupported lengths deflection, the energy supply system is even sometimes desirable to be constructed in such a way that it is not completely straight without effort can be stretched, so that only with long unsupported lengths a straight form due to the weight of the system, whereby a forms certain elastic deformation. They are called energy supply systems can only be brought into a straight shape with effort "preloaded" systems.
  • Protective element rows can also be manufactured with any prestress. All that is required is that the wall and / or cover segments are not all are molded on one side of the floor segments, but alternately on both sides. In this way there is enough space for the Wall segments, but especially the cover segments in their entire length can be made greater than the total length of the floor segments, which just results in the preload.

  • chains require the production of special end pieces, which requires a corresponding effort in tools and logistics. Molded end links for energy supply systems in large quantities are therefore particularly cheap. This effect will still be there reinforced by the fact that the end pieces are not just holes or certain ones Have forms for attachment to other components, but directly as Recording for connection means of lines are formed.
  • the end piece with pre-shaped receptacles for electrical and / or to equip pneumatic and / or hydraulic plug connections, as will be explained in more detail using the drawing as an example.

  • Row of protective elements consists of protective elements attached to at least one band or injection molded onto two or more threads at predetermined intervals or be cast on. It is also possible to have several protective elements to cast on a tape or threads at the same time. That way creates a belt-like system which has many favorable properties combine extruded energy supply systems and energy supply chains can. In particular, production of any length is possible, whereby nevertheless the one-piece remains.
  • the flexibility and resilience the system can be selected by the choice of tape or threads and be influenced by the spacing of the protective elements. Basically can different materials for the tape or the threads and the protective elements are used. However, it is also possible to do both to manufacture the same material.
  • Another method according to the invention which is a particularly preferred one Execution is the manufacture of a one-piece series of protective elements from given length in a single mold or injection mold.
  • Raised Tool costs for this one mold are significantly lower for spraying machines, assembly and assembly tools as opposed to only a single component has to be handled and folded while at many components are handled from chain links formed energy chain must be and numerous post-processing steps for extruded systems required are.
